I think that FreeDoom would benefit greatly from a new/modified palette. It is a simple change that would dramatically alter the feel of the game, helping to differentiate it from Doom. Has this been discussed or attempted before?

One of the goals of Freedoom is/was to support playing PWADs. PWADs might have their own additional graphics which would be mangled in unpredictable ways by a radically different palette.

If freedoom ever split into the "base" compatibility IWAD and a freedoom "game" PWAD, it could be done in the latter.

As mentioned above, it's not a good idea to change the palette for PWAD compatibility reasons. I personally don't want to see a palette change.

All the resources themselves are already changed. A new palette that alters the hues of the existing color ranges won't "mangle" PWAD compatibility any more than having all the IWAD textures and sprites be replaced.

See PalPlus for an example of a significantly altered Doom palette that maintains PWAD compatibility.

Yeah, I think a new palette with the same basic color ranges as Doom's could potentially do wonders to set Freedoom apart from Doom. It might also help to make Freedoom a little more interesting in its own right.

I would've proposed this myself by now, were I not too lazy to actually design said new palette and its colormap on my own.

Well all you really need to do is make the first palette¹. All the others, and COLORMAP, are calculated from it by scripts.

That said, must you change it? The modern fashion to tweak the palette of your megawad is annoying and I wish it would go away.

Why not? All the graphics themselves are different already; it's not like this would be the first thing to differentiate FreeDoom's appearance from that of the original game.

If a PWAD provides some graphics, such as its own textures, then changing the palette in Freedoom will mean the texture in the PWAD will render differently in freedoom than in vanilla doom.

For example, if you swapped the red range in the freedoom palette for purple, a PWAD which had a texture with a red square in it would have a purple square when played with freedoom. That's no good.

Hence why a 'compatible' palette would use the same basic color ranges, but with different RGB values for each index, each of which would still roughly match the corresponding color in Doom's palette.

Besides, if a PWAD provides graphics, they're usually based on existing Doom graphics, and so will probably look out of place in Freedoom anyway.

If Freedoom is "illegal" for allowing you to play those PWADs, then so is every modern source port.

Not unless the source ports are providing functional replacement IWAD resources to make these PWADs with IWAD-based custom graphics playable without ownership of the IWAD.

And even if it's the case anyway (and I don't believe it is), it wouldn't be illegal. It would just be a violation of DOOM's EULA at the most. And that's a civil matter, not a criminal one.

This is, of course, what I'm suggesting, Some wads do this already: changing the blue range is especially popular. Even subtle changes can have a profound, individual effect without "breaking compatibility" with any art.

There are scenarios where this isn't necessary. Someone may have only one IWAD and yet still play a PWAD that contains resources (modified or not) from another IWAD. You see this all the time with Doom PWADs that have Heretic or Hexen textures, music, etc. But guess what, the source port doesn't check to see if the PWAD contains id resources (very difficult to detect modified resources anyway, a simple checksum doesn't cut it). And without code, you can't run checks. Freedoom is not code, so playing baby-sitter is impossible.

If you go through with this palette change, at least make sure it looks okay with classic PWADs like Icarus, The Darkening, Memento Mori, etc. (basically everyone listed in the top-100). Because otherwise you're effectively crippling one of the key uses of Freedoom.

I agree with hex11.

Many subtle color choices in level designs were made relying upon the doom palette. It is very easy to change a nice two tone color effect into garish, or no visible effect at all.
Tools (like xwadstools) out there support it inherently, and will provide a copy of it.

The only palette change that will work is one that is functionally identical (but with subtle differences) to the point that it is indistinguishable except to those who want to argue that about it.

Yeah, and those levels were also made relying on Doom's textures. FreeDoom isn't using those, either.

I was thinking of my levels and the how much trouble I had finding a flat texture with color close to the wall texture I was using, just so I could put a good color on a door sill, the bottom edge of a door, or the underside of a door frame. A palette change is going to mess all of those up. Every place I was trying to match colors, or find a color that would approximate some effect or represent something.

I could change my levels, but the good visual PWAD did the same thing, and a palette change will change the intended appearance even more, and we cannot retroactively change them.

What happens to a PWAD that has its own special textures, based on the DOOM palette.

You mean anything, because you can break the law with practically any item or thing produced.

Freedoom is in danger of infringing copyrights if it can be argued that the palette is a creative aspect or piece of DOOM. PLAYPAL is not very different from GENMIDI, which was removed for possible copyright concerns.

Here is an example of what happens when a new palette is applied to textures based on the Doom palette: http://www.doomworld.com/php/screen...=pal_plus04.png It's not the disaster you suggest, and that example shows a sweeping palette change. Many wads change only the blue range and the effect is still distinctive.

Your profound, individual effect is my cue to curse the fashions of modern mapping, open the wad, and delete the PLAYPAL lump.

Also, gifs don't store indexes into the PLAYPAL lump, they have their own palette. Consider what will happen if the PLAYPAL lump does not match the palette of all the gifs in Freedoom's source tree when Deutex tries to build the wad.

It looks terrible to me. Colors are dull and washed out, this looks nothing like the original game. If this screenshot would have been posted in this topic without any text, I would have assumed it was to defend the idea that a mere palette change can completely butcher the art.

Yeah, and those levels were also made relying on Doom's textures. FreeDoom isn't using those, either.


The gist of your argumentation seems to be about pointing out other flaws. That doesn't make much sense to me, two wrongs don't make a right ; surely, just because Freedoom is inaccurate in some points doesn't mean it should strive to be purposefully inaccurate, nor that it should try to be even more inaccurate than it already is.

Not flaws, differences. The counterargument seems to be based on the misconception that without changing the palette, FreeDoom looks exactly like Doom.

FreeDoom's purpose is to use original (differing from Doom) content while maintaining pwad compatibility. A new palette can easily help differentiate the game from Doom without compromising compatibility.

RjY: Your complaints confuse me. FreeDoom is not a megawad for Doom, using Doom resources but changing the palette. It is a separate game with its own resources and style. The similarities between Doom and FreeDoom, by design, lie in their gameplay, not their appearances.

Phml: That particular palette is not my favorite either, only an example of a palette that changes the game's feel without breaking compatibility. You complain that the result "looks nothing like the original game (ie Doom)", but FreeDoom's goal is not to imitate Doom's aesthetics so slavishly that the palette must be identical. The idea that FreeDoom's visual differences are "flaws" or "inaccuracies" betrays a fundamental misunderstanding of the project.

This is what I — respectfully — disagree with. I don't think it's possible to vary the PLAYPAL or COLORMAP significantly and guarantee to preserve compatibility at the same time.

I suppose the question is what constitutes a significant change. I spent some time running through FreeDoom using the UDM3 palette ( http://www.doomworld.com/idgames/index.php?id=13058 ), which modifies the blue and green ranges but otherwise leaves the palette unchanged (as far as I can tell). Compatibility remained intact, but the new hues lent the game a different feel. Perhaps you could try noclipping around a favorite megawad in FreeDoom with that palette and see what you think?

You could say that more so about all of Freedoom's new graphics which often don't look great alongside stuff made for DOOM in a PWAD. The palette difference would be consistent along all the resources, new in Freedoom and old in the PWAD, so its incompatibility would be lesser than that of the new graphics that can clash stylistically. That is, someone downloading Freedoom and trying a mod with it will more likely notice the differences between the graphics from one and the other than any effect from the palette, which will only be more evident to someone trying the same mod with DOOM.

I see two artists (jute, essel) giving arguments in favor of trying a new palette, and two coders (jon, fraggle) which helped initiate the project years ago without much concern about artistic quality, as if it would come up anyway. That quality may indeed be arriving, but with proposals by artists that may ask for changes to allow it best.

Here are some screenshots of FreeDoom with the UDM3 palette being used to play Memento Mori and Hell Revealed. I don't think it could be reasonably argued that the palette changes break compatibility, but they clearly change the game's "feel", just as (for instance) replacing the demon with a worm or replacing the chainsaw with a futuristic saw changes the game's feel without breaking compatibility. In fact, these latter changes are far more radical than changing a blue color to a slightly different blue color. But all these instances further FreeDoom's goal to be a complete new game based on the Doom engine that retains PWAD compatibility.
